Subject [jira] [Created] (CASSANDRA-2911) Simplified classes to write SSTables (for bulk loading usage)

Simplified classes to write SSTables (for bulk loading usage)

                 Key: CASSANDRA-2911
             Project: Cassandra
          Issue Type: New Feature
          Components: Core
            Reporter: Sylvain Lebresne
            Assignee: Sylvain Lebresne
            Priority: Minor

sstableloader only stream existing sstables. If you need to load data existing in another
form (json, csv, whatnot), you need to first write the sstable(s) to load. The recommended
way to do this is either to use json2sstable or to modify it if your input is not json. Modifying
json2sstable is however more involved than it needs to be, you'll need at least some basic
understanding of a bunch of internal classes (DecoratedKey, ColumnFamily, SuperColumn, ...).
Even for json input, you can use json2sstable only if your json actually conform to what is
expected and even then, good luck to someone that want to add counters.

This ticket proposes to add a simple interface to write sstables.
